For which rifle? Google search turns up M1, M14 and K-31 (never heard of that one) clamp-on muzzle brakes.

Don't really work and most after a few shots, you'll have to recover 25 yards downrange if it doesn't damage your gun in the process.

So I'm guessing you don't have a threaded barrel? Most likely, your best option is to swap out the barrel (or upper), or alternatively have a good gunsmith thread your existing barrel. Not what you wanted to hear, I'm sure, but that's what I would do.
